ASF GitHub Bot logged work on BEAM-7802: ---------------------------------------- Author: ASF GitHub Bot Created on: 13/Aug/19 19:40 Start Date: 13/Aug/19 19:40 Worklog Time Spent: 10m Work Description: kanterov commented on issue #9130: [BEAM-7802] Expose a method to make an Avro-based PCollection into an Schema-based one URL: https://github.com/apache/beam/pull/9130#issuecomment-520978853 Changing AvroCoder will definitely break compatibility, especially streaming pipelines reading from PubSub or Kafka. In addition, SchemaCoder for Avro isn't as good (yet) as AvroCoder. As an example, it would serialize enums as strings, that is very inefficient when shuffling data. Another source of problems is that it doesn't support all Avro features. I believe once it matures we it could be the default, but we aren't there. In any case, I think it's a good exercise to think where we want to put SchemaCoder and how we are going to evolve AvroCoder, so, probably we should start a threat on dev@. The code looks good. I agree and support your motivation on making fewer things private, but I don't find it practical to break it now given that we know for sure that there are codebases relying on it being public to avoid limitations of existing APIs, so I propose to postpone this before things stabilize. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

The idea is to expose a method in schema.AvroUtils to ease this. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
